SACCHARINE TRAP.

Specification of Letters Patent.

Patented May 9, 1922.

Application filed November 3, 1919. Serial No, 335,303.

To all whom it may concern.

Be it known that I, GODFREY Encnn, Sn,

citizen of the United States, and resident of Brooklyn, county ofKings, and State of New York, have invented certain new and useful Improvements in saccharine Traps, of which the following is a specification.

The present invention isa saccharine trap entrainment between the evaporator an the condenser.

The objects of the invention are to provide a simple and practical construction which will hold and retain the entrainment out of the path of the vapor current so that once caught the entrainment will not again be picked up and carried away with the vapor.

In the construction herein disclosed I have shown the trap in the form of an annular chamber interposed in the neck of the evaporator between the evaporator and condenser and provided with ribs or battles for collecting the syrup in a pocket disposed be low and out of the direct current of the vapor.

I11 the drawing, which illustrates but one exemplification of the invention, Figure 1 is a vertical sectional view of the complete apparatus.

Figure 2 is a horizontal sectional view taken on substantially the plane of line 2--2 of Figure 1.

The evaporator is shown as of the usual construction, consisting of a shell or body 5 rovided with an outlet neck 6. This neck is formed with a vertically disposed discharge passage 7 in one side thereof and bafiles 8 are shown provided on the opposite vertical edges of this passage. These baffles may be provided by simply turning out the walls of the neck at the opposite edges of the opening. In addition I have shown these baiiie walls as provided with inwardly projecting angularly disposed ribs or flanges 9, which exert a further bafiling effect upon the outflowing vapor. Surrounding the neck portion or the evaporator is.an annular wall 10 which, with the Wall of the neck, forms an annular chamber 11 constituting the trap proper. The two annular walls described are shown connected at the bottom by inclined wall 12, which forms one side of a collecting or drainage pocket in the bottomof the trap. The trap is closed at the top by a cover 13, which for the purposes of repair and the like is made removable, as indicated.

14 designates the condenser which is shown connected with the trap by means of a conduit 15. This conduit enters the trap at a point substantially diametrically opposite the discharge 0 "ening 7 and at this outlet point additional afiie walls are provided, said baflie walls consisting of a flange 16 projecting inwardly into the annular chamber around the outlet opening.

In the illustration I have also shown the outer surrounding wall provided with inwardly projecting vertical ribs or flanges 17 extending into the annular chamber at opposite sides of the discharge openin 7 and down below the lower edge of said openings (Figure 1) so as to conduct the entrainment below the opening and so out of the direct path of the vapor. In this way the entrainment is in effect positively carried away from the vapor current and the possibility of its being again caught up and carried oil by the vapor is thereby eliminated.

With the construction described the vapors passing from the neck of the evaporator to the condenser are subjected to a bafiiing action and the entrainment is caught by the ribs or baiiling walls described, all of which drain into the annular pocket provided in the bottom of the trap. The accumulation of entrainment is drained off from the bottom of the trap in any suitable way and it will be noted that the entrainment as it collects is out of the path of the current of vapor and so is not affected by the constant flow of vapor.

What I claim is:

.1. A saccharine trap having a conduit for the flow of vapor in a substantially hori zontal plane constructed to produce a change in direction in the flow of vapor and having an entrainment collecting chamber open thereto at the point of such change in direction but partly below the direct path of vapor flow therethrough and an entrainment trapping pocket on an outer wall of the conduit substantially at the point of change in direction of the vapor flow to thereby catch the heavier particles thrown outward by centrifugal force from the vapor by the change in direction of movement and extending from the horizontal plane of direct vapor flow down into the entrainment collecting chamber to thereby catch the heavier entrainment carried by the vapor and thrown outwardly by centrifugal force and to hold the same at one side 01 the vapor path and conduct it directly down into the entrainment collecting chain her. 7

' 2. In a saccharine trap an annular wall havmg an opening in one side thereof and outwardly extending flanges at opposite.

in nct n-th ew th vel et ade?? 3. In a saccharine trap an annular wall having an opening in one side thereof and outwardly extending flanges at opposite edges of said opening and projecting outwardly beyond the annular wall and entrainm'ent catching ribs on the inner faces of said outwardly projecting flanges and providing entrainment collecting -pockets ada ted to drain down outside the annular wal an entrainment collecting chamber at the foot of said annular wall to catch the drain from said pockets and a wall surrounding said"annular wall and providing inconjuntion therewith a vapor conduit, andu'p'right' ribs on the inner face of said outer surrounding wall at opposite sides of the opening in the inner wall and forming additionalpockts for the trapping of entrainment.

'In witness. whereof I hereunto set my hand, this 31st day of October, 1919.
